Vibration @ Hwy Speeds

I would loosen and re-tourque your pinion flanges. Do you have play between ftont and rear flange of TC?

 

I had a weird 35-45 mph vibration. Back tc flange was hair loose and one u joint needed a ton of grease to push through all the seals. Grease would only weap out of one. Caught it early. Axle hop maybe?

 

Aftermarket wheels that aren't hub centric?

 

We’re gonna find out soon if my problems are my tires, picked up some 4Runner wheels and tires. Gonna give them the factory trash edition spray paint.

 

In my hunt to solve the problem I got the wheels road force balanced and rotated again, replaced the carrier bearing and no change. I'm not sure where you all are feeling it most but mine definitely seems to be most noticable in the floor with the steering wheel just seeming to resonate lightly with that shake as opposed to being a wheel shake.

I'm leaning heavily towards it being my aftermarket CVs but I'd like to rule out most other things before swapping them out again. I still have my OEM axles but they're pretty rusted and have torn boots so they'd be for testing purposes only.

My other thought would be engine/trans mounts. Anyone else run down the rabbit hole?
